Regarding auto populate follow up or baseline

Dear All,

Can you guide me i want to autoupdate while followup 1 then auto update base line date, If fill the form follow up 2 then auto fill the last foloow up date 1 to continue till last followup.

You'll want to use Entities. See https://docs.getodk.org/entities-intro to get started. Do also try the tutorial at https://docs.getodk.org/tutorial-community-reporting.
